I am having trouble getting my car emission tested.
At two different places, the emissions test equipment could not establish a communications link with my car.
Last night I used VAG-COM release 303.1 and it passed the OBD-II function test but Alex Peper's Vehicle Explorer Scan Tool rev 1.05 could not communicate with my ECU.

And you can read stuff from the ECU, then there must be a setting in that Vehicle Explorer Scan Tool that is misconfigured (serial port settings are the problem 9 out of 10 times)
However, it may not even work - I've never tried hooking up non-VAG tools to my car. Sorry I couldn't be more help... maybe someone else could verify this for me (us) ?

Yes I do.
That was the first thing I suspected. I removed the radio only to find out that the K-line going into the aftermarket radio wire harness was a no connect on the other end.
Strange thing is that VAG-COM works perfectly. I am able to get a reply back from all of my controllers when doing the system scan and the OBD-II function test reports no issues.

Even though I hated doing it, I brought the car to the local Audi dealership as a last resort.
Amazingly the car passed the emissions test without any of the communication problems that I experiance at the previous two testing stations.
Now I can have some fun by digging into VAG-COM and learning everything about this cool tool!
